Studies On The Process And Engineering Design Of The Material Extraction Workshop Of Relinqing Tablet

Relinqing is a kind of pure traditional Chinese medicine formula, which distilled from the unadulterated Chinese Materia Medica-Touhualiao originated from Gui Zhou province, and mainly used for the treatment of infection of urinary system. A. Relinqing tablet is the improved preparation based on Relinqing granule. The article mainly studies the process , quality standard of Relinqing tablet and the design of extracting workshop.On behalf of the study of the process of Relinqing tablet, firstly, the best technical parameters are established through the studies of the extractiing process of Relinqing tablet, which provide the basis on the detailed design of the process. Secondly, the technical parameters of compression and film coating are also established through the studies of the manufacturing process of Relinqing tablet, which also provided the basis of the manufacture of this product.On behalf of the study of the quality assay, the identification of the raw dosage form was adjusted, the item of the content mensuration was added, and the quality standard was also revised. All of which provided the basis of ensuring the quality of Relinqing preparation.The extracting workshop can disposal 1500 tons of material medica annually. So in the period of the design of the distilling workshop, the extracting process should not only involve Touhualiao, but also other Chinese herbs. The refluence extracting technology was adopted in the process to save the energy (such as three times evaporation concentrator can save 40% of stream, hot circumfluence extraction concentrators can save 50% of stream and 30% of solvent).The workshop was designed for perpendicular production process to make use of building rooms availably and save the areas and transportation equipment. Otherwise, perpendicular design not only retrenches the pump but also makes transportation pipeline short and vertical, which avoid accumulating of the raw material, and can be cleaned easily. this design met the requirement of the pipeline collocation in GMP. On the residue of the medicine, the automatic cleanup system of the waste residue track was adopted. which not only turned traditional waste residue cleanup system into easy automatic opreation, but also the working condition are also improved, at the same time, the contingency of scald. Can also be avioded.GMP is the basic requirement in the process of the pharmaceutical industry, according to the principal of GMP, the cleaning manufacturing area was designed as 100,000 degree.
